Wd357 is the sole operational survivor of 111 Baldwin Locomotive Works locomotives that were used in New Zealand. In fact for a number of years Wd357 was the sole surviving Baldwin railway locomotive of any class (several other Baldwins have since been recovered from locomotive dumps).
One of 18 of a class built in 1901, Wd357 is one of four originally allocated to South Island service. The Wd class was versatile, working all types of trains in regular service with New Zealand Government Railways until 1935, when she entered service with the Timaru Harbour Board, working its quarry until 1966.
Wd357 was donated to Canterbury Railway Society in 1967, and became the first locomotive in steam at Ferrymead Railway on 11 March, 1967.
